Linus Torvalds f0691533b7 virtio/vhost: new features, performance improvements, cleanups ... This adds basic polling support for vhost. Reworks virtio to optionally use DMA API, fixing it on Xen. Balloon stats gained a new entry. Using the new napi_alloc_skb speeds up virtio net. virtio blk stats can now be read while another VCPU us busy inflating or deflating the balloon. Plus misc cleanups in various places. Signed-off-by: Michael S.
